| Abstract (English): |
【Objective】 To explore lactic acid bacteria (LAB) resources in raw camel milk. 【Methods】 Raw camel milk samples were collected around Nanshan mountain in Urumqi, Xinjiang and the strains were isolated by the plate dilution method. The 16S rRNA gene sequences and morphological observation were carried out to clarify the taxonomic status of the strains, and edible safety characteristics such as detecting hemolysis and harmful metabolites. 【Results】 Results showed that a total of 29 LAB strains were isolated and identified, which belonged to 4 species in Leuconostoc and Lentilactobacillus; the tested strains could tolerate 0.5% bile salt, 5% NaCl, and showed good high temperature resistance, milk peptonization, anti-oxidation, different enzyme activities, and antibacterial properties. None of strains were positive for hemolysis and produce nitroreductase. No biogenic amines were produced from amino acids by strains except T12.【Conclusion】 The LAB obtained from camel milk in this study has good fermentation characteristics and food safety.

【目的】挖掘和获得原驼乳中的乳酸菌资源。【方法】采集新疆乌鲁木齐县近效南山周边原驼乳样品, 采用平板稀释法分离菌株, 观察比对16S rRNA基因序列测序和菌株形态学特性, 分析菌株分类学地位, 并检测菌株溶血性和有害代谢物质等食用安全性。【结果】获得29株乳酸菌, 经鉴定其归属于Leuconostoc、Lentilactobacillus两个属的4个种;菌株均可耐受0.5%胆盐, 5%NaCl, 且具有较好耐高温、牛奶胨化、抗氧化和抑制细菌等特性;所有菌株均无溶血现象, 不产生硝基还原酶;除T12外, 均利用氨基酸不产生物胺。【结论】从原驼乳中获得的乳酸菌具有良好的发酵特性和食品安全性。 [ABSTRACT FROM AUTHOR] |
